The high beams won't work, and when I try to turn them on, all my other lights dim bright and the motor bogs down a little. And if the lights switch, they cut completely off and I have to hit the switch 4-5 times to get low beams to return.

My car has 93000 miles.
My car has an automatic transmission.
